Hippa, Heikki & Kurina, Olavi, 2013, New species and new records of Manota Williston (Diptera: Mycetophilidae) in the Neotropical region, Zootaxa 3686 (2), pp. 101-139 : 122-124

Manota papillosa sp. n.

Figs. 12 A–C

Male. Colour. The specimen is extremely faded and the colours are difficult to estimate. Head brownish, face yellow. Antenna pale brownish. Clypeus and mouthparts pale yellowish. Thorax yellow, medial part of scutum and scutellum brownish. Legs unicolorous yellowish. Wing pale brownish; haltere yellow with dark brown knob. Abdominal tergites yellowish brown, sternites paler than tergites. All setosity pale, yellowish or brownish. Head. Antennal flagellomere 4 similar to Fig. 10 A ( M. micula ). Palpomere 3 of maxillary palpus with apicomesial thumb-like extension, with 3 apically curved sensilla; palpomere 4 with parasegment; palpomere 5 ca. 1.2 times longer than palpomere 4. Number of strong postocular setae 9. Thorax. Anepisternum setose, with 28 setae; anterior basalare non-setose; preepisternum 2 non-setose; laterotergite non-setose, episternum 3 setose, with 8 setae. Legs. Mid and hind tibial organs absent. Wing. R1 meeting C well on the basal half of the costal margin; the sclerotized part of M2 extending to the level of the tip of R1; wing length 1.5 mm. Hypopygium (stained with Chlorasol black). Figs. 12 A–C: Sternite 9 laterally fused with gonocoxa, posterior margin transverse, not just reaching the middle length of gonocoxa, anterior margin deeply incised, the setae similar to the adjacent ventral setae of gonocoxa. Ventral mesial margin of gonocoxa angled; there is no posterolateral lobe on gonocoxa, the ventral setae unmodified. Parastylar lobe membranous, covered by the gonocoxa, with 1 seta. No paraapodemal lobe observable. Dorsal mesial margin of gonocoxa lobe-like broadly expanded towards the medial line, otherwise simple. Number of juxtagonostylar setae two, the ventral one a simple seta, the dorsal one flattened megaseta with a whip-like branch, both arising from a common basal body which is shorter than the setae. Anteriorly from the juxtagonostylar megasetae there is a plate-like lobe bearing anteriorly a strong megaseta and posteriorly three shorter pointed megasetae. Otherwise the dorsal setae of gonocoxa similar to those on the ventral side except for a row of very long setae in the middle of the posterior half. Inside the gonocoxa there is a conspicuous membranous part bearing numerous finger-like papillae and which is concave towards the medial line. Gonostylus flat, subtriangular, the apicomesial and apicolateral corners lobe-like, the former with two setae, the latter with one dorsally curved seta. Aedeagus narrowly subtriangular, the sides concave, the apex curved ventrad. Hypoproct extending posteriorly just over the base of gonostyli, the number of ventral setae (sternite 10) ca. 15 on each half. Cerci mesially separate.

Female. Unknown.

Discussion. The exact character of the papillose membrane inside the hypopygium of Manota papillosa is not known to us. Similar membrane in the same position is also seen in M. appendiculata ( Fig. 4 C). Reminiscent membranous structures are also seen in many other Manota even if the size of the papillae are smaller and can look more like scales (see e.g. under M. squamulata in Jaschhof & Hippa 2005). Often they are only vaguely seen and not mentioned in the descriptions or marked in the drawings.

In the non-setose anterior basalare and laterotergite, sternite 9 fused laterally with the gonocoxa, the membranous parastylar lobe with one seta, the 1+3 megasetae situated anteriorly from the juxtagonostylar megasetae on the dorsal side of the gonocoxa, the subtriangular gonostylus with a long seta at the apicomesial angle and with a curved seta at the apicolateral angle, Manota papillosa resembles M. bisulca , M. corcovado , M. diversiseta and M. vexillifera . It differs from all by having the dorsal mesial margin of the gonocoxa lobe-like widened towards the medial line and by lacking a distinct posterolateral lobe on the gonocoxa.

Etymology. The name is Latin, papillosa , full of papillae, referring to the papillose membrane inside the hypopygium.
